anyone loose their history to go back after opening the article page? I had to double check I didn't open in external tab. browsing on firefox.

Firefox quarantines Facebook sites in a separate container (with its own cookies and browsing history, etc.), losing back button is an unfortunate side effect.

Curious when the folks at ClickHouse are going to decide to spin its custom rewrite of ZooKeeper in C++ (ClickHouse-Keeper [1]) out into its own separate project.

Off-topic, but does Zookeeper have features that etcd doesn't provide? etcd seems to be simpler to operate at a glance.

My understanding is that they have different consistency models and different APIs. I think etcd might be better suited for more use-cases, but I don't think migration of existing systems is straightforward.
